When entering links to RFCs in VisualEditor, the results are not links. When in Visual Editor, as soon as you type "RFC 2328" it turns blue and looks like a link. When you save it, the link is gone.
Here is an example: https://ndg.nenawiki.org/wiki/Sandbox#Entered_in_VisualEditor.
Apparently there may be problems with RFC links in VisualEditor when Magic Links is enabled. https://phabricator.wikimedia.org/T145589
Is magic links ($wgEnableMagicLinks) enabled on our sites? (nenawiki.org and ndg.nenawiki.org)
If so, could you disable it?
Thanks
Mike
